It is. You're verbalising an incredibly tired stereotype about millennials (and I'm Gen X, so don't try pulling the "offended millennial" card) as if it's a real thing in response to people complaining about the already pretty gruesome grind in GT7 which has now more than doubled.
Weird thing to say given that you have no idea how I play the game...
... but it also savagely misses the point. The most effective way to earn money now requires 200 repeats to earn one - just one - of the high value cars in GT7. Every other way requires either many more repeats, or slightly fewer repeats but considerably more time.
Whichever way you choose to earn credits - whether you "vary between" races or not - will require dozens of repeat runs. And of course by the time you have saved up for one of these cars, which the game is sold on the premise of being able to drive, you might not be able to buy it any more.
There is a giant chasm between "spend 14.5 hours grinding this one race (or way more time grinding a bunch of others in order to earn enough money to buy ONE high value car" and "the problem with people these days is they want everything right now". People complaining about the first thing are not people to whom the second thing applies by sheer dint of complaining about the first thing.
The game simply needs more game. There's about 20% of GT Sport's activities, on a game that could have launched with all of these races - and more, considering the 25% larger car list and four additional track locations. If it took 200 hours to get through instead of 20, like GT Sport, and had high-value late stage races, like GT Sport, nobody would be bitching about the grind. At least not yet, because they'd still be playing through the game right now.
